Yes, my understanding is that the galley ways in the head are huge and no matter what the oil pressure or engine rpm. the pressure of the valvecover and the crank case is always the same. BUT, you will never hear anyone tell you to have less block ventilation. some hp can even be had if you use a pump to suck the pressure out.

Kami header to straight 2.5" pipe all the way to comptech muffler... needless to say, VERY loud!!

imo let the car sit until you have an s300 or something similar + wideband.

Ok guys so I am having a bit of trouble. I have the RC 440 injectors. Model SL9-440 and I can't figure out what lower grommet to use to make them fit properly into the JRSC manifold. Someone please help and give me some real answers. Can't find anything helpful after searching a few times.

I had the same issue with my Deutschwerks injectors. Ended up buying an assorted o-ring box from NAPA, then fitting the correct o-ring that would work both around the injector and inside the manifold. Also, I doubled up the O-rings to make sure it all sealed up.

I also had to get longer bolts and fabricate spacers to get the factory fuel rail to fasten the injectors to the manifold.

its a nightmare, thanks for the input

Can you post a picture of the issue you are having?

Do we have an opinion on a b20 (gsr head) in regards to the popular gsr inlet itr exh cam combo?
Would there be any gain running itr/itr with the larger displacement at around 10psi
thanks

Update:

I went to get my new setup on E85 tuned Saturday (3/11/2017)...

B18c5 / Jrsc / LHT cooler / MVM stepper pulley / itr crank pulley / MVM 3.8" nose pulley / kamikaze header / 750cc RC saturated injectors / s300

This is the first time I've driven the car since putting the A2W Bosch pump on and running water through the system.

On the dyno it started missing before the tuner could even start tuning.

It started losing water from the a2w cooler even though there were no leaks.

Well it looks like the LHT is leaking into cylinder #1.

Pulled plug #1 and found water drops in cylinder.

Shut off A2W pump and all the missing went away.

I'm fuming bc of the amount of time and $ I've spent on this LHT only to have it be a piece of ****!

But the best part was when it wouldn't engage vtec.
I guess maybe the pressure switch or vtec solenoid is dead also.

So dyno results at 7psi: 160whp at 5k rpm and 137ftlb at 3k rpm with no vtec.

Fml.

Gutted for you dude...
I've found lht quite quick to respond to messages on Facebook, I'd definitely mention it to them.
have you disturbed the vtec solenoid wiring when inspecting the issue or something

Black R

I haven't called LHT bc honestly what's the point?

They modified the manifold for me probably a year ago, and I haven't spent much time getting the car back together since then.

Best case scenario would be me having to tear the whole blower down again and ship it off to them to fix.

That's such a pain in the ***; if I take the blower off, I'm going turbo.

I didn't disturb the wiring - and the solenoid clicks when I jump it - but that's not always an indication that it's working - in this case it's not.

It has the same amount of miles on it as the motor (83k), so idk why it would die randomly, but I guess maybe from non-use it can seize up?

Sorry to hear Black R. That's really frustrating.

HeikDiesel

R I feel you with the frustration, I still would contact them to fix it so you can at least attempt to recoup some of the money out of the project.

Also that those WHP numbers, is that on 91?

Let's get some turbo builds going

Luckily I got the LHT kit used but in working order. I have the same setup as you except I'm using a larger crank and no kami headers. Hopefully all goes well with mines when I start the install later this month. If you ever decide to go turbo and want to get rid of your kami, I'd be interested.

This was something I wrestled with for a bit but I finally pieced everything together. If I'm not happy with the JRSC, then I might go this route...
I almost gave up on the project but hopefully I get the JRSC in this month without any issues.

CX-Adam

I'm looking for recommendations. I think I need to replace my head gasket and possibly shorten the alignment dowels. Should I first drop the charger and remove the IM or leave it all on? The only reason I'm asking is I'm afraid I'll drop the cap screws into the intake runners and/or recreate vacuum/boost leaks.

~sp33~

That's scary. I sent my LHT manifold back twice because they kept stuffing it up (from Australia too). I'll be sure to pressure test it before i install it. You'd think for the cost they would test them before sending them back to the customer.

JRCivic1

First, let's get you past the frustration and agony of this setback and get you to a point of logical thinking and reasoning. Once there, talk to John at LHT... he is a reasonable guy and will likely work out an amicable solution for the both of you. Once fixed, you get back on the dyno and make it right finally. Remember, this was your FIRST choice... you have already considered other options... and this option was what fit you best in your vision for the car.

Now in the off chance that you cannot get it right, you could consider a DIFFERENT supercharger option behind door number three !!! C'mon Black R... join me and walk the path less traveled. You would STILL be supercharged...

Black R

Once I settle down, I'll give them a call.

​​​​​​​This is on E85.

Black R

That's the thing: they said they DID pressure test it prior to sending it back to me...

I remember reading the horror stories about LHT leaks into the manifold, but figured those were isolated incidents.

Black R

I hear you, and yes I'm frustrated.

The reason I said turbo is for simplicity.

example: I have a Greddy turbo kit on my itr and it has performed flawlessly.
It was easy to install, spools at 3k, makes 300whp at 10psi, and is a ton of fun.
It has fewer moving parts, and honestly I can't complain about anything it does.
It's been on the car for idk how many years and has been dead nuts reliable.

Now bc I was building an autox car, I thought a jrsc would be more reliable for hot summer events (less heat in the bay). And make power lower down in the rpm band.
But with all the belts and pulleys, and now heat exchanger and lines for the cooler, it's seeming less reliable - potential for leaks and slipping or shredding belts and whatnot. :/
And with newer ball bearing turbos, I could have a super quick spool as well.

I guess I'll see what LHT has I say about it, but I have a sour taste in my mouth right now.

Are you suggesting a kraftwerks kit? I hadn't considered those bc of $, need for power down low, and again slipping belt potential.

Joshua Coop

I want turbo, I'm about ready for it as soon as I have my fuel system ready, but I gotta lame code 9/ cylinder position sensor killin, so far 3 different distributors! The b16a2 starts sputtering, and that's how I know when its goin out. About 6 months ago I put in an msd ignition,with external coil, seems to have helped, code still there, but now looks like that coil is having problem.

*Also I know this is kinda off topic, but I'm trying to get my two posts in so I can start a new thread about my issue here.

HeikDiesel

I guess that sounds about right now that I think about it

JRCivic1

Does anyone have any pictures of some of the new Canadian steel JRSC replacement upper and lower tensioner assemblies ??? I was contacted via PM about how to install them, and since I have never seen any live, and I just assumed that they installed just like the original kit parts (shame on me), I never gave it a second thought or looked into it. After seeing the pics I was sent... I am unsure how the upper tensioner assembly connects to the OE upper alternator bracket and how the top of the alternator is "located" during the install. Any help would be appreciated.

Black R

Well I just got off the phone with George at LHT.

I asked if any other customers had leaks like this and he said no.

He did say if I send the manifold back to them, he'll weld it up if there's a leak.

​​​​​​​So there's that...
